Polarization Model and Control in Fiber-based Bidirectional Systems with Reflections

La, William 07 January 2011 (has links)
We present, for the first time, methods to model and control the polarization of the output lightwave of a bidirectional fiber-optic system, in which the lightwave propagates through polarization control elements in both directions. Using the dynamic eigenstate (DES) principle, we built model to simulate the behavior of the polarization evolution. In a bidirectional system with one control element, we extracted system parameters from experimental data and achieved less than 3% angular deviation between modeled and experimental state of polarization (SOP). The theory was further validated by varying the input SOP to the bidirectional system. Our method can be extended to predict the SOP of a system with multiple actuators. Furthermore, combining our deterministic control method and a feedback loop, we are able to control the output SOP to be within a mean angular deviation of 5.5% from the target SOP, with as few as three iterations.
